为更清楚地展现事故致因因素间的相互关系,并考虑因素间关联关系对于节点重要性的影响,本研究根据2018-2023年国内526份高处坠落事故报告,利用BOW(Bag of Words)方法结合人工分析提取涵盖人、物、环境、管理四方面的高处坠落事故致因因素集,以共现频次为权重,应用复杂网络理论构建高处坠落事故致因模型,并分析加权前后网络的度中心性、介数中心性、接近中心性、聚类系数的特征特性.最后,结合灰色关联分析理论,定量分析高处坠落事故致因因素的重要程度.研究结果表明:高处坠落的致因因素为,未正确佩戴防护用具,安全教育培训不到位,发包不规范,现场安全管理不到位,安全意识淡薄;应高度重视和管控这些致因因素,减少施工高处坠落事故的发生.
Analysis on the Cause of Falling Accident in Construction Based on Weighted Network
In order to more clearly show the interrelationship between the factors causing the accident and consider the influence of the correlation between the factors on the importance of the node,this study based on 526 domestic height fall accident reports from 2018 to 2023.By using BOW(Bag of Words)method and manual analysis,extracted the causative factor set covering people,objects,en-vironment and management.With co-occurrence frequency as the weight,complex network theory was applied to construct the causation model of height fall accident.The characteristics of degree centrali-ty,intermediate centrality,proximity centrality and clustering coefficient of the network before and af-ter weighting are analyzed.Finally,combined with the grey correlation analysis theory,the importance of the factors causing height fall accidents is quantitatively analyzed.The research results show that the causative factors are:not wearing protective equipment correctly,safety education and training is not in place,the contract is not standardized,the site safety management is not in place,and the safety awareness is weak.We should attach great importance to and control these causes to reduce the occurrence of falling accidents at construction heights.
